What connection method is more reliable for PP pipes with small diameters? ? ? For example, for PP pipes with a diameter of DN40 or less, is heat fusion socket welding more reliable or threaded connection? ? ? The operating pressure ranges from -0.1 to 1.0 MPa, and the operating temperature is at room temperature.
I think welding is more reliable
I’ve heard from pressure vessel suppliers that welding generally offers better reliability and sealing performance compared to threaded connections. However, since the pressure in your case isn’t very high, either method can meet your connection requirements. I think you should choose whichever method is more convenient depending on the actual situation – whether welding or threaded connections is easier to use
Use hot melt welding; it provides good sealing performance. If it is not regularly maintained.
It depends on the fluid medium inside the pipe; if it is non-corrosive, threaded connections can be used, while welding is a better option if the fluid is corrosive
Welding is better; PP flanges are less strong, and their sealing performance is not very good, especially in pipelines under high pressure.
Use heat fusion bonding. . . . This method is also used for ordinary PVC pipes
For PPR pipes with small diameters, heat fusion welding is the better option, as it ensures a secure connection and durability
Hot melt welding is relatively reliable and ensures quality.
Welding is better, as it ensures reliable tightness and also enhances strength.
Hot melting is still the best! One of the projects I worked on was related to PP pipes! It’s wastewater treatment – just like your work pressure and working temperature!
Hot melt welding is relatively reliable, with guaranteed quality. It provides a secure connection and is durable
